Granted: 1901-07-27
Abstract: 12,985. Johnson, G. W., [Boehringer & Sohne, C. F.]. June 25. 4 : 5-Diacetyldiamido-2 : 6-uracil (4 : 5-diacetyldiamido-2 : 6-dioxypyrmidine), which serves as a starting point in the preparation of pharmaceutical or medicinal compounds, is produced by heating uric acid with acetic anhydride, with or without a condensing-agent such as pyridine, until an ammoniacal silver solution is not reduced by heating it for a short time with the product of the reaction. The uracil derivative is separated from the 8-methylxanthine which, as is described in Specification No. 526, A.D. 1901, is also produced in the process, by boiling the product with water and evaporating the solution to crystallization. Triacetyldiamido-uracil is also produced if the acetic anhydride is in excess, but it is less soluble than the diacetyl compound, into which it is converted by saponification with boiling water or a weak base or acid. The diacetyl compound is converted into a monoacetyl compound by treatment with an alkali.

Abstract: 3488. Danforth, H. C. Feb. 11. Gas burners.-Relates to an arrangement of nozzles for regulating the How of gases &c. Fig. 2 shows the invention as applied to a bunsen &c. burner for controlling the gas supply. The tube A has holes B for the admission of air, and carries at the top end a frame to which is attached a cylinder of a gauze and a bood. A nozzle F is screwed or adjustably secured in the lower end of the tube, the nozzle having a conical &c. head, in the apex of which is a hole G. An inner nozzle H screwed to the gas-supply pipe is adjustably secured in the nozzle F, and has a shoulder I on the top, a ring of holes K in the side, and a hole J, of smaller area than the hole G, at the apex. Gas can pass from the nozzle H to the space between the nozzles, and, by altering the area of the annular ring between the shoulder I and the outer nozzle, the supply of gas can be regulated. The adjustment is performed by moving the nozzle H relatively to the nozzle F, a lock-nut L securing the nozzles in the adjusted position. When the shoulder I is in actual contact with the nozzle, the supply through the holes K is entirely cut off. The areas of the holes G, J determine the maximum and minimum supply. Instead of a single hole G or J, a number of holes may be formed in the top of each nozzle.

Abstract: 20,432. Llewellin, W. M. Sept. 19. Time-checking apparatus for workmen. Relates to improvements in apparatus of the class described in Specifications No. 23,257, A.D. 1901, and Nos. 2627 and 7881, A.D. 1902. The cylinder A, Fig. 1, which may be coated with elastic material, is mounted on a spindle A' in sliding bearings C, C' provided with limiting stops D, D'. The pinion B' is driven from a clock through a flexible shaft, and gears with the toothed wheel B. Fig. 2 shows the type-wheel E and inking- ribbon J". The bearings of the cylinder A are shifted to bring the cylinder against the ribbon and type-wheel by means of a fork H<1> on a lever G<1>, pivoted at G<11> and rocked by means of a plunger F. The type-wheel is moved up and down on its shaft to print on the various horizontal lines of the diagram sheet by means of a grooved collar, fork, and vertically-moving rack. The inking- ribbon spools move with it, and the spools are provided with divisions for ribbons of three colours. By means of a finger lever the spools can be shifted to bring any desired ribbon into use. Diagram sheets Q<1>, Fig. 6, may be attached to an endless band Q of cloth, india-rubber, &c. passing over cylinders P, each of which is associated with a type-wheel R. The type-wheels are driven by clockwork, as described in Specification No. 2627, A.D. 1902. The cylinders P are driven through bevel gearing from a shaft S, driven continuously or intermittently from the clock. The intermittent drive may be effected by mutilated gearwheels with Geneva-stop movement, or by a starwheel X, Fig. 9, provided with a snapping detent V and driven by the pins w<1>. A signal may be given to indicate that the clock requires winding, by means of an electric contact device, which closes a bell circuit when the clock weight has fallen to a certain point ; or the lateral movement of the fusee chain e, Fig. 11, of a spring-driven clock may close the contact at f, f<1>. The type-wheel is accurately aligned when an impression is made, by means of a plunger h, Fig. 14, with V-shaped end, which is caused to enter between the teeth of a wheel g, Fig. 12, on the shaft of the type-wheel. The end h<11>, which is V-shaped in plan, is angular in elevation, as shown in Fig. 14. The Provisional Specification describes a duplex pointer or plunger for this purpose. When a single line on the diagram sheet is insufficient for the record, means may be provided for raising or lowering the cylinder on its shaft sufficiently to print a second line below the other. This raising or lowering may be done automatically by the clock, in the manner described in Specification No. 2472, A.D. 1881. The same result can be obtained by shifting the type-wheel, or by using two numbered lines on the sheet for each operator, and giving him two numbers on the index plate for successive use. The clockwork movement described in Specification No. 4653, A.D. 1883, may be used in the machines described in the three Specifications first quoted above.
